Croppers in the Burnett


12344.jpgBased in Monto, Queensland, the project is trialling the use of legume crop rotations and composts to reduce nitrous oxide (N2O) emissions, improve soil health and increase productivity on cropping land in Queensland’s western Burnett region.

The project will trial, measure and demonstrate on the following farm practices/technologies:

  • integration of legume crops in the cereal cropping rotation
  • the inclusion of soil amendments
  • minimum tillage practices
  • the use of nitrification inhibitors

The project aims to provide local croppers with tangible data and agronomic advice on:

  • Dynamics of daily N2O emissions
  • Cumulative N2O emissions under different management practices over the fallow and cropping season
  • Comparison of annual or seasonal N2O emissions between the new farming techniques and the conventional management practices (e.g. bare fallow vs. soybean fallow, different soybean residue management practices, displacement of fertiliser N with biologically fixed N, conventional tillage vs. no-till and with/out use of nitrification inhibitor in urea)
  • Identification of the best farming system that results in the lowest N2O emissions without sacrifice of cropping yield, and
  • Analysis of daily N2O fluxes in relation to major driving factors such as soil mineral N, water content and climatic conditions.
